To N whom it may concern.' p

Be it, known that l, Sncoxno L. Casema,

a citizen of the United States of America,

residing aty the borough of' hilanhattan, cityof New York, in the county of New York and State of New York` have invented certain Anew and useful 4Inlproveniente in Machines for Making' Battei'y-(ups. of which the. following is a specification, reference being had therein to theY acconnianying drawings, forming` part. thereof.

My invention relates to machines for autinnati-cally making,` the zinc cups or open soldered in place within one end ofthe tube,

the. cup heini: left open at the top. Herctofore. as av matter of common and extensive practice in the manufacture of' batteriesfthese cups have been niade altogether bv hand and,

so far as l ain advised` the machine `of iny present invention is the rst for the pui pose of doing: this work automatically.

The inain 'object of inv invention is to decrease the cost of manufactureof dry batteries hyinakinir the zinc cups thereof au# tematica-ily hv machine which have hereto ,fore been niade by hand labor. Other'object-s of iny invention are to produce a niachine for this purpose which is strong, durable, efhclent. dependable, convenient, and i coinparativel)1 sii'nplein construction and in expensive of manufacture. Other objects and advantages of in v invention willjhereinafter appear. i'

Mv invention includes features ot' con struction and col'nbinations of parts and'subcombinations thereof as will appear fromthe following description.

I shall now descrlbe thebattery cup inachine embodying my invention illustrated in the' accon'ipanymg drawings and shall thereafter pointent iny invention 1n claims.

. 'It is to be noted and tak-Xen-V eration that the s heetzinc fr-oy not sufliciently rigidand strong Ato:rpjarrnit 105' of hooked or clenched joints such as arte/ommonlyV employed in tin cans; For this reti# son the soldering ofthe joints must be Iielied upon altogether-,the side seam'of' the cup body bein a simple lapped `joint and l105 the bottom dis .beingheld 1n. place at the inside of the ,body altogether. bygsol-f .Moreoven .while by furthe largest-` number of'batter .clips are of com-para-` tively' smaljlsizejt e nature of z inc is such- 111) that 'these'cups'cannot be formed by draw'- ing'operations as this wouldl leave them cracked, porous and worthless as containing cells for' batteries. Thereforev in providing an automaticmachine for doing-this work of 115l making zine battery L'cups, special' requirements must be kept `in mind, and the "maf chine for this purpose now to be described produces zinc battery cups o'ffsubstantial-ly he same construction'that were .formerly `120 vmadeby hand, One ofthe most-common sizes of these battery. cups is about two and .i one-quarterinches in length by one'andonequarter inches 1n diameter. That is the size of cups produced by the machine Vi-llu'stratex'tl 1.125 l in theaccompany-ing drawings, although' it is 'to be'under'stood that -simllar aut'omatic machines embodying my invention. may be constructed for producing either larger or# smalier sized cups, and infact. siinilargmaleo.

chirfe has beenbuilt for producing cups of a smaller size than that mentioned. i.

In the machine enibodying my invention `illustrated in the drawings, a strip of sheet zinc 1 of a width corresponding to the depth of the battery cups to be produced is taken from a supply reel 2 and is pushed b v feed rollers 3 and 4 between. a loweil bed plate 5 and an upper guide plate the latter being shown asprovided at thev back with an abutment flange. The bed plate and guide plate are both rigidly mounted and arespaced apart a trifle more `than ,the thickness of the sheety nretal strip land are rounded their adj aoent. forward edges for the easy admissionbf the end of the strip 1 between them, as clearly appears in they ln the' drawings, particularly in Fig. 11. i space or gap between the' feed rollers 3 and ,20 .4 and the shghtbv spaced guide plates 5 and the sheet metal strip 1 is guided by means ot'thinguide plates 7 and 8 and is pressed down upon the latter by a spring-ljn'essed pin 9'. "G'rooied guide bars 10 Asupport the zinc strip 1 at its edges and guide it to thefeed rollers 3 and 4. The upper feed roller 3 is Strongly spring-pressed toward the lower one f1-,by means of` a pair of coiled thrustsprings 11 acting upon guide blot-ks l 12 slidablyl mounted in the frame of the ma Chine, as appeal-sinv Fig. 16 for example. The feed rollers 3 and 4 are geared together for concurrent actuation by means of spur gears 13and 14, the former being fixed upon a shaft 15 which carries the upper feed roller 3 and the latter being fixed upon a sleeve 16 which carries theA lowerfeed roller 4'." The sleeve 16 is journaled both in the frame of the machine and upon a longitudinal shaft 17 extended substantially from i endto end of the machine, as clearly appears in Fig. 1. The feed rollers 3 and 4 are intermittently positively operated by means now to be described.

Q Gears `and a `Geneva movement are provided'for "positively driving the lower feed roller 1 fromthe longitudinal shaft A mutilated 'gear 1 8, `constituting the, driving element of the Genevan'iovement, is'ixed Aon the outer end ofthe shaft 17 adjacent to the spur gear 14 `of thelowerfeett roller l, and intermittently actuates 1n a well knownmanner an intermittentgear 19 constituting the drivenelement of the Geneva movement. 5'5 In the construction shown the driving elepment 18 imparts one-third of a rotation to the `driven elelnentlt) for each rotation of the shaft .17, so thatiglitwill V.require three rotations of the shaftwl? and'driving ele- V': ment 18 to impart oncompl'ete rotation to thedriven element\19, the .rotation 'of the latten being intermittent with intervening periods of rest. as is Well understood. The

` driven element' 19 ofthe Geneva movement I'` bolted to the spur gear' 2.0 as clearly appears in the drawings, partieularl in Figs.

1li and 1T. and both of the gears 1H and 2U are fixed upou a stul-i-.shaft .'l which isjourualed iu the frame of the machine. Fig. lo partit-ularly. and the spur gear 2l) meshes with the 70 gear 14 ofthe lower feed roller 4. l1' will now be understood that the strip of sheet '/.inc `l, will be imerulittenl'ly positively fed rearward over the bed plate 5 and beneath the guide plate o for providing at. proper inter vals blanks from which the cu-p bodies or tubes are formed.

' The supply reel 2 is driven in the forward or unwimling direction b v means of 4a small belt which passes over a small pul- ,ley on the outer end of the shaft 1T and around a larger p"ulle 23 fixed. ou the shaft of the rcel 2. -The purpose of this' is to provide a certain amount of slack iu the strip 1 for lessening the strain on the feed-85 rollers 3 and l so that a positive ftaulingforward of the strip l will-be assured. The reel 2 is turned forward' a litth` faster thau is necessary and oecasiomlll)v is turned battle ward by hand to take up the slack when it becomes too much in the strip 1. A volte 24.1Ji\'()ted to' the ends of ,the upper feed roller shaft 15 and a forwardly projecting level' Q5 pivoted on the frame of the machine are providedrfor raising the upper feed roller 3. against the tension 'of the.` springs 11 when this becomes necessar for an \Y pur ose in the olieration'of the machine. eans are provided for automatically stopping the machine should the supply of sheet. zinc strip 1 on the reel Qbecome exhausted, as will now be described. ,A main drive shaft 26 is journaled in andextends` transversely through the fnameoi' the may chine at the front end thereof' and at the 105 front sidel of the machine is connected to the longitudinal shaft 17 to drive the latter b'pnieans'of intermedia/te connections [in:L c uding spur gears 27, bevel gearslQS, a short .vertical shaft Q9vand upper bevel gears 110 A Weighted trigger lever 31 isfpivoted ont the frame ofthe maehineand left freie-fat its'forward end and is supported by' the' strip of zinc 1 so that in the absence of the` zinc strip 1 the lever end will drop between lill` pressed vtoward \its'operating position by a 125 coiled thrust spring 35, al pears most-clearly in Fig. 18.
